WINTER TRAVEL TIPS
1) Get your car inspected or tuned up ahead of the winter season. Check, and repair as necessary, your battery, antifreeze, wipers and windshield washer fluid, lights, heater, defroster, and tires.
2) Keep your smartphone batteries charged before a trip and invest in chargers to use in-car as well.
3) Having a winter weather kit in your car can help you out when Mother Nature has a winter weather temper tantrum!
Put these in your Kit:
- Snow Shovel
- Ice Scraper
- Jumper cables
- Sand or kitty litter to add traction
- Extra blankets or clothing
- Non-perishable food
- A first aid kit
- A tow rope or chain
- Water (don't leave in car when parked to avoid freezing)
- Extra gloves (especially when going through the rockies ;) )
- Road flares (to help you be seen if stranded on roadside)
4) Plan ahead: Don't be afraid to cancel or re-schedule a road trip if winter weather appears dangerous. Don't be caught in white-out conditions, heavy snow, blizzards, or ice storms unless it's an absolute emergency.
5) If you are caught in winter weather beyond your driving capabilities - don't be afraid to pull off at the nearest exit and get a hotel for the night or wait out the storm. The most important thing is you taking yourself out of harm's way.
